GZnIN DIN G-MACHINE.

To all whom it may concern: w

Be it known that I, Joan JAY Lnsonnn, a citizen of the United States, residing at Mount Carmel, in the county of Wabash and have invented certain new and useful Improvements in Grinding-Machines, of cation. I,

My invention relates to improvements in grindingmachines, the present embodiment of the invention being particularly designed and adapted for use in grinding engine cyl inders and in winch a grinding member. or'

zibrading tool is sii'mlltancously rotated and revolved around the axis of the cylinder in contact with the wall an d fed longitudinally thereof so that the entire surface will be ground and any imperfections therein removed in the grinding operation.

The. primary object of my invention is.to

provide a generally improved grinding ma chine of this class or exceedingly simple in construction, cheap of manufaeturelantl eflicient in use.

object of the invention is the Afurthe'r provision of improved bearings of great strength and rigidity adapted to carry and ma ntain the parts in proper relative posi tions in the various movements or adjustments in the grinding operation as Well as the provision of improved driving'mechanism for-rotating and reciprocating the respective parts while in operation.

A still further object is the n-ovision of improved means for controlling and adjusting the'various parts t'o'meet the varying igencies of actual service.

With the above mentioned, and other ends in view, the invention consists in the novel construction, arrangement and combination of parts, hereinafter described and illus trated inon'e of its embod' ncnts in the accompanying drawings, and particularly poi ntcd .out' in the appended claims.

two parts so that endswith annular recesses or ball receiving race-ways 4", and centrally located bearing openings 4, adapted to receive and contain a rotatably mounted or sleeve 6, said support or sleeve 6, being provided at its top with a gear wheel 6, said support or sleeve being preferably made in tive to the bearing sleeve 9, by means of a key member 10.

As a means of connecting and drawing the bearing collars 9 and 9?, toward each other and securely retaining the same in the seat portions 8, of theopenings 8, when adiusted, a connecting rod 11, is provided, (see Fig.'3,) said rod being provided with tapered shoulder portions 11, extending through and adapted to expand split portions 9%, of the bearing collars when the nuts 11", are drawn up.

The bearing collars f), and 9 are adapted to be adjusted circumferentially when the nuts ll'gare loosened through the medium of a wrench adapted to be inserted in the wrench receiving openings 9, of the adjusting collar 9", and the collars are provided with eccentric openings to receive and contain the lower end of the tool carrying driving shaft 12, and the upper .end 'of the shaft bearing sleeve 9, the latter being secured in. the adjustable collar 9", by means of the retaining nut 13,-thre:fi ded on the up- .per end of the shaft carrying sleeve 9.,

By reason of the eccentric location of the tool carrying drivingshaft 12, in the collars 9 and 9*, it is apparentthat the shaftl2, may be readily adjusted so as to hold the I grinding wheel or element 3, in contact with the inner surface of the cylinder and to a fixed distance from the center-thereof and as the bearing support or sleeve 6, is revolved through the medium of the gear wheel 6, and the actuating mechanism hereinafter described, such grinding tool or ele-. .ment 3, will travel bodily in a circular path entiresurface so as to efl'ectively grind the of the object being operated upon.

The upper end of the shaft '12. s provided with. arflexible shaft or coupling 14,

geared bearing support the same may be longitudinally adjustedto take up wear and adjust the annular ball bearings 7, the, lowerfpart removable guide= flanges in a bracket 1", extending upwardly tom the stationary support or housing 1. The gear wheel 15, is provided with a suitable key member or projection operating in a keyway 12, of the shaft 121 As a means of transmitting motion to the parts'a, 6 HHd'HQ, a vertical driving shaft 16, is mounted at one end in the gear housing 1", and is supported at its upper end in suitable bearings 1, in laterally extending bracket arms 1. A gear wheel 17, located between the arms 1", adapted to transmit motion to the gear wheel 15, and a vertically movable gear wheel 18,,on the shaft 16. is adapted to transmit motion to the gear wheel 6, and isza means of holding the ear wheel 18, in alinementwith the 6", and causing the gear wheel 18, to be moved up 'and down with the reciprocation of the carriages, and the geared'bearing sleeve 6, said gear wheel 6, is provided with 6", adapted to receive and contain the outer edges of the gear wheel 18. The gear wheel 18, is provided with a key adapted to operate in a key-way 16, of the shaft 16. The, shaft 1-6, may be provided with a bevel-gear 19,:meshing with a-second bevelgear 20, on the motor shaft, ahd as, a means of transmltting'motionito the gear wheel 6*,

whereby the latter is adapted to reciprocate the'carriagel. the lower end of the-shaft 16, is provided with a worm QIQineshing with a on a horizontally extending shaft mounted in suitable bearings in the gear housing 1, and the shaft -is provided with a worm 23*, meshing with a gear 2-], carried "on a shaft mounted in bearings 26. and the shaft 25. is provided with a pinion 27, n'ieshing with the gear 5, operating in therack l.

It will also be apparent that by reversipg the motor the reciprocation of the parts will be correspoi' dingly reversed and it will' be seenithat an in'iproved machine of. great strength and rigidityin which the bearings may be readil v adjusted, is produced.

From the foregoing description, taken inoon'ncction 'with the accompanying drawings, the operation and advantages of my invent-ion will be readily understood' a r Having thus described one of the embodiments of my invention, what I ,claimand gear w eel having tadirection of rotation or pered shoulder portions extending through and connected to said split portions whereby the latte1'may be. expanded and secured in adjusted position. v .L
